HARRY VISSERING, OF CHICAGO, ILLINOIS, ASSIGNOR T0 HARRY VISSERING ANDCOMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

ALARM-VALVE.

To all whom t may concern Be it known that I, HARRY VIssERING, a citizenof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inAlarm Valves, of which the following is a specification.

My invention has reference to valves of the rotary type especially, andto valves for admitting fluid contained under pressure to an apparatusoperable thereby, and proposes the provision of an improved form ofvalves having means for graduating the admission of the fluid and awarning or alarm port to call to the attention of the user the fact thatthe valve is open, vto the end that pressure may not be unnecessarilyexpended, the operation of the device prolonged, or the mate.- rial fedthereto or coming therefrom lost, tending to unnecessary wear and tearof the parts or destruction of material; valves of this class beingfound to be especially useful as part of track sanding apparatus, airbrake systems and other devices governed from a locomotive cab and otherplaces at a distance from the place of operation.

The principal objects of my present invention are the provisions of animproved construction of valves of the character specified, one whereinthe warning'port will be closed at all times when the main operatingports are closed, one wherein the closure of the main operating portswill simultaneously close the warning port, the provision of an improvedform of alarm valve device wherein all ofthe ports are carried onoppositely disposed members, and wherein such members are held togetheragainst displacement in order to insure registry of the ports; theprovision of a valve device of the character described wherein theoperating ports are graduated in size to the end that fluid pressure maybe gradually admitted to the actuated device and a waste of the initialpressure or material fed thereby, or too violent starting of theactuated device, may be avoided; the provision of such a valve whereinthe warning port will be open during the entire time that any of theoperating ports are open, and one which is constructed to admit of readyre-grinding or replacement of certain of the parts of the valve withoutdisturbance of other parts thereof or of the connecting conduits, theprovision Specification of Letters Patent.

of a valve of the character described which is adaptable for admittingpressure to a plurality of devices, together with additional benefitsand advantages which will hereinafter be disclosed.

In attaining the foregoing objects as well as others which will bemanifest to those who are versed in the construction and operation ofvalves provided for the purposes contemplated by my present invention, Ihave provided the construct-ions which I have illustrated in theaccompanying drawings wherein- Figure l is a sectional elevation of avalve embodying` my improvements. Fig. 2 is a view partly in sectiontaken on the line II-II of Fig. 3. Fig. 3 is a sectional view taken onthe line III-III of Fig. 2, and Fig. 4 is a sectional elevation ofanother eX- emplification of my improvements.

Referring now more particularly to Figs. 1 to 3 of the drawings it willbe app-arent that in carrying out the embodiment of my invention hereillustrated I provide a valve casing 5 which may be. mounted insuit-able position for operation by means of the bracket 6 with which itis held in engagement by the lock nut 7, the said casing having at 8(Fig. 1) an inlet connection to a high pressure conduit and at 9 and 10(Figs. 2 and 3) outlet connections to low pressure conduits, theconnection 8 communicating with the connections 9 and 10 by thepassages, 11, l2 and 13. The casing 5 is also provided with a passage 14for a purpose to be hereinafter more particularly described.Communication between the high pressure passage 11, and the low pressurepassages 12, 13 and the passage 14, is normally interrupted by the valve15 whose stem 16 eX- tends through the casing and carries an operatinghandle 17 provided with a latch 18 adapted to be held in contact by aspring 19, for which a housing is provided in the handle, with notchesin a segment 2O at the periphery of' the casing. The valve 15 isdesigned to be held in Contact with the seat 21 by means of the fluidpressure, and opposite the stem is provided with a hub 22 rotating in abearing formed in the cap 23, passages 241 and 25 being formed in thehub 22 to the end that the pressure on all parts of the valve may beequalized and a vacuum at the end of the hub 22 and ensuant leakageavoided. On viewing Fig. 1 it will be ob.- served that at the end of thepassage 14 I have provided an alarm device which comprises a hollowcasing 35 here shown as formed integral with the valve body 5 and havinga passage 36 and a port 37 leading therefrom and venting to theatmosphere,

the casing 35 being provided with a valve 3S slidably movable thereinand adapted to close the port 37 when the operator presses thereupon,displacement of the valve 38 from the casing 35 being prevented by ascrew 39. To permit the establishment of operative connection betweenthe high pressure passage 11 and the outlet passages 12 and 13 andsimultaneously the alarm device, it will be observed that I haveprovided in the valve 12 a series of passages 26, 27 and 23 adapted toregister successively with the passage 9 as the handle is moved in onedirection, and 30, 31, and 32 adapted to register successively with thepassage 13, as the handle is moved in the other direction; likewise thepassage 33 adapted to establish connection with the passage 14 when thehandle is moved in either direction, by means of the irregularly shapedgroove 34 formed in the seat of the valve 15 and communicating with thepassage '14.

Referring now more particularly to Fig. 4 wherein I have illustrated analternate form of valve embodying my invention, it will be apparent thatthe valve herein illustrated is in all substantial respects similar tothat shown in Figs. 1 to 3, save thatthe valve 15a instead of having asingle plane face contacting with the seat 40a, is wedge shape and theseat is not only made comformable thereto, but is also cut away at 41 inorder to receive the said valve and permit of such grinding as may berequired to make a very close lit, thereby insuring a greater' degree oftightness than is feasible with the valve shown in Figs. 1 to 3, andfurthermore that instead of the hub 22 projecting into the bearing 23,in this alternate form of construction I have formed the hub 221 and thebearing 25a to provide a housing for a spring 42 whose pressure againstthe cap 23 and valve 15 will tend still further to keep the valve 15a intight contact with its seat 40a.

In the operation of apparatus wherein a valve of my improvedconstruction is utilized, when the user moves the handle 19, causing theport 26 and passage 12, or the port 30 and passage 13 to register, atthe same time the port 14 will be caused to register with the groove 34and air at high pressure will rush through the passages 11, 33, 34, 14,36 and 37 making a hissing or whistling sound which will continuallyattract the operators attention to the fact that the valve is open andthe device controlled thereby is in operative connection, until thehandle bei again moved onto the lap position indicated at 43 (see Figs.1 and 2).

In cases where the device is in uninterrupted use as where track isbeing sanded on a long grade, the warning sound may be shut oli'temporarily by pressulre of the finger upon the valve 38 which willclose the port 37, but it will be noted that the device cannot be ,leftin operative condition without the knowledge of the operator, since whenthe finger is lifted from the valve 38 the pressure will again forcesuch valve outward and the alarm device will again become operative.

It is to be observed that when the handle 19 is moved to the first notchthe smaller of the three ports 26, 27 and 28, or 30, 31 and 32, isbrought into communication with the corresponding outlet passage, andbut a comparatively small amount of pressure allowed to escape, thatwhen a further turn is given to the next notch a larger port 27 or 31will be opened, and that when the valve is pushed to the eXtreme limitof its movement the largest port will be uncovered, though by virtue ofthe fact that the groove 24 is continuous from end to end the warningsound will accompany any movement of the -valve suiiicient to uncover'any one of either of the series of ports. By the operation heredescribed it will be obvious that the user, as in cases where the valveis used in connection with track sanding apparatus, will be able tofully control the amount of material delivered and thereby greatlyhusband not only the supply thereof but also be much more economical inthe use of sand at the point of contact of the locomotive with the railonly, whether such locomotive be running forward or backward, whichconstruction is advantageous in this that in the use of two sets ofvalve devices, the waste of sand incidental to supplying it both infront of and behind the point of contact, is avoided.
